Summary: This document contains a summary of albedo estimates produced through 'Approach 1', including the figures listed below:
This figure shows several plots related to the final albedo estimates produced by Approach 1.
This figure shows an initial attempt at a mixed effects model analysis.
Correlation matrix of explanatory variables:
Model in R: Random effect is month nested under site ("LocalityName")
